THE BEST! & BETTER THAN ORIGINAL COLT! (26/12/2010)

I have fired an original select fire full-auto COLT SMG (M16/9mm) and have had many malfunctions using 147 grain 9mm ammo. I bought a Rock River Arms 9mm upper receiver assembly and this HAHN Top-Loading 9mm Conversion Block. I also am using original COLT M16/AR15 32 round magazines. I have not experienced any malfunctions with my converted AR15 using 115 grain & 147 grain 9mm ammo in semi-auto or full-auto modes of fire. I also recommend the ENIDINE Hydraulic buffer for recoil reduction and slower rate of fire in full-auto mode. Call me if you have any questions.Cell [@]. GUN SLINGER VIDEOS

Great 9mm block (17/03/2012)

Function has been 100% with 1000+ rnds of misc ball and long ogive HP ammo in following setup, Spikes lower, Spikes 9mm buffer, RRA Upper with CMMG ramped 9mm bolt and CMMG barrel, Metalform, Colt and Spikes mags. Installation is easy as long as you are comfortable performing basic assembly on an AR lower as the bolt catch must be removed and reinstalled. Works just as well as my dedicated Colt. Mileage may vary depending on the quality of your lower.

Works Very Well (31/05/2018)

Works well with C product metal form mags. Drop in is easy to take in & out if your swapping uppers. I did have an issue with the mag catch not poking out enough to grab the magazine. I went with a 9mm Mag catch and then had to take material off the base by the post. This caused it to can't into the wag well more with success. No fault of the drop in.

Fits and works great! (17/02/2013)

As the headline says, this block fits and works great and the finish is fine. The Metalform 32 round magazines slide in and out and lock in place smoothly. The rounds feed and eject perfectly and the bolt locks open when the magazine is empty.
What more could you ask for?

Great product (10/11/2016)

I bought this to use in my SBR lower with a10.5" upper. Functions perfectly with metalform mags with 3 different bullet weights. Easy in and out in about 3 min. At the same time I bought a designated 9mm lower for a 7.5" pistol. Nothing but malfunctions using the same mags.
